Overview

LF3347 DEVICES INCORPORATED High-Speed Image Filter with Coefficient RAM LF3347 DEVICES INCORPORATED High-Speed Image Filter with Coefficient RAM DESCRIPTION The LF3347 consists of an array of four 12 x 12-bit registered multipliers followed by two summers and a 32-bit accumulator.
The LF3347 provides four 256 x 12-bit coefficient banks which are capable of storing 256 different sets of filter coefficients for the multiplier array.
All multiplier data inputs are user accessible and can be updated every clock cycle with two’s complement data.
The pipelined architecture has fully registered input and output ports and an asynchronous three-state output enable control to simplify the design of complex systems.
A 32-bit accumulator allows cumulative word growth which may be internally rounded to 16-bits.
Output data is updated every clock cycle and may be held under user control.
The data inputs/outputs and control inputs are registered on the rising edge of CLK.
The Control/Coefficient...
